Problem with lines showing up in Carbide Create?

When i import files somtimes from Inventor or AutoCAD as dxf files, sometimes the lines are missing. Take a look at the pictures below. Does anyone know why this happens? I have tried to “block” everything on AutoCAD, no change.

Overlapping geometry seems to confuse things — please send any problem files in to and we’ll see what we can do to help you puzzle it out and add it to our suite of test files.

The community does have some notes on DXF export for Carbide Create at: Shapeoko CNC Router, Rigid, Accurate, Reliable, and Affordable

  • Import DXFAutoCAD
  • 2000 DXF format (model geometry only, base model scaling) export from the desired face (not isometric view)
  • 2004 Lines

Hopefully that will help.
